Lady Gaga (Stefani Germanotta) and various companies have been hit with a federal RICO lawsuit alleging that contrary to public representations they retained a portion of the donations collected through the "Lady Gaga Japan Earthquake Relief Wristband" effort. The class action suit, filed in the U.S. District Court for the Eastern District of Michigan seeks a range of damages, including punitive and treble damages. No response from Lady Gaga yet, but presumably one will be forthcoming shortly.
